I have a Sharp Aquos LC-32AD5. Had it for almost three years now, and I never knew about the proper calibration techniques so I never did them.
Lately, the picture quality has been on a decline. I first noticed it while playing games on my PS3, but now I’m starting to see it in the digital broadcast channels as well. The picture just seems to be a bit blurry/pixelated, with a bit of aliasing. I called the repair center today, but they told me that they can’t really make an accessment unless they actually see the TV for themselves.
Before I get to the point where I summon a repairman, I was just wondering if it is possible for the quality on a HDTV to start failing, what some of the possible factors are, and if there’s anything I can do on my end to correct it. I’ve tried searching for info on the web, but most of it is geared towards initial maintainence, or problems of a different nature.
